Head Mounted Input Device Using Mems Sensors
A person who has limited control over their limbs cannot do much for themselves. If this person stay at home, they need others assistance to do a task. Task also implies those concerned with the PC. Hence, to make them handle and control a PC easily, in the authors' paper they design economical wireless mouse and keyboard that emulates it functions. So users will not have any physical connection while interacting with their computer system. Their model uses MEMS accelerometer to detect the user's head movement in order to direct mouse position on the monitor. Also clicking events are generated by detecting complete eye blinking as a selection mechanism. The system has been demonstrated to perform mouse movements and clicking events successfully.
